Title: RE: Signal Translation (Severely OT, with apologies) (longwinded explanation of parameters) Hi John What follows is longwinded, and may only make sense to (ex-)hardware technauts like myself.  But you asked! I don't think I gave enough data to fully comprehend the problem.  Requiremen

Title: Signal Translation (Severely OT, with apologies) Hi I have a peculiar request - I want to take a 4-20 ma level transmitter signal and adjust it slightly by a non-linear equation based on another 4-20 ma signal.  I can envisage several ways to do this involving custom hardware, some incl

2004-04-13 Thread Smith, Blair
Hi We have a LabVIEW program under strict revision control. Presently, the code is at the LabVIEW Rev. 5.1 level. We are about to make changes (minor) to that code. Version upgrades are way beyond scope. My preferred editing machine is at the 5.1.1f level, due to other-project upgrades. Has an

Rick I don't know if it's still the case, but in some instances in the past, you could quit LabVIEW and the AO would continue to generate. VERY disconcerting for users; however, there is little you can do about it other than designing in timeouts, watchdogs, etc. in hardware. Just be aware that i

RE: Waveform graph legend

Chad We have in the past used a transparent plot overlaid on the base plot. This gives you independence between your data plot and the limits plot, easing some of these issues. Of course, it creates other issues, like synchronizing graph scales, etc. But for our case(a multi-trace chart), where

Clipboard persistence of code snips (was Rant...)

Jason, John, Greg This "clipboard preservation of otherwise closed VIs" issue has bitten me several times in the past. Although I'm currently "just" a lurker, it has annoyed me enough that I cannot resist chipping in on this one. If NI finally got rid of this pestilence, I wouldn't complain. Th

Daniel, Simon This sounds suspiciously like the behaviour of a tip-strip. They're programmatically settable and appear when you hover over the control/indicator - will that do what you want? Blair -Original Message- From: Simon Whitaker [mailto:[EMAIL PROTECTED] Sent: 2004/02/18 09:59 To
